I'm trying to configure mine server to enable the Apache's "worker" version supporting PHP5. I have googled for hours, and all I find is either confusing/vague info. or tutorials for older Ubuntu versions (I don't even have such "conf.d" folder here!).
After the OS installation (including LAMP Server, of course) I have done this:
sudo apt-get install libapache2-mod-fcgid php5-cgi sudo a2dismod mpm_prefork sudo a2enmod mpm_worker sudo service apache2 restart
Then all I get is a message like this:
* Restarting web server apache2 [fail] * The apache2 configtest failed. Output of config test was: [Tue Dec 23 04:40:25.939993 2014] [:crit] [pid 5992:tid 140022236075904] Apache is running a threaded MPM, but your PHP Module is not compiled to be threadsafe. You need to recompile PHP.
As far as I seen, there's some files needing to be edited, but since these tutorials are for older/other versions, I couldn't even find them. So my question is, where are the files I need to edit, and what do I have to edit in them?
